Primary Outcome Measures:
  • Change in Maximal Acitive Range of Mothion in knee extension [ Time Frame: 9 weeks ] [ Designated as safety issue: No ]

Estimated Enrollment: 50
Study Start Date: January 2009
Estimated Primary Completion Date: May 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: 1
Patient will receive post-surgical standard of care treatment with standard Physical therapy and NSAIDs.
Experimental: 2
Patients will be treated with the Standard of Care physical therapy and NSAIDs as well as a Knee Extension Dynasplint that includes tension chambers.
 Device: Knee Extension Dynasplint
Dynamic Splinting utilizes the protocols of Low-Load, Prolonged-Duration Stretch (LLPS) with calibrated, adjustable tension to increase the Total End Range Time (TERT) to reduce contracture. The Knee Extension Dynasplint for the Experimental group will have tension chambers delivering therapeutic treatment from the device.

Detailed Description:

The purpose of the study is to evaluate the efficacy of dynamic splinting for knee flexion contracture following a total knee arthroplasty.
